CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 62/758,690, filed on Nov. 11, 2018.

BACKGROUND

A command line interface is a user interface in which a user enters commands in the form of a string of text characters. The command line interface is a text-based interface in which the commands are manually typed. The command line interface accepts commands in a designated input field which are then executed by a command line interpreter. This type of user interface is advantageous over a graphical user interface (GUI) where a user uses a mouse or fingers to click images of icons to access files or programs and/or to execute various operations. The command line interface is faster and more efficient than a GUI since it is composable, that is several tasks can be specified in a single text string thereby eliminating numerous interactions with the GUI.

The use of a command line interface requires a user to be familiar with the commands supported by the command line interface and the correct syntax of the commands. The availability of good reference documentation for the commands may be limited. This is often a problem where there are a large number of commands with various sub-commands and parameters which may be used in numerous ways.

SUMMARY

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

A command assistance tool is provided for a browser-enabled command line interface of a cloud service. The command assistance tool learns the syntax of a command from usage patterns found in telemetric data, scripts and user documentation and forms templates based on the usage patterns. There may be several templates for a command where each template represents a different usage pattern with a unique combination of subcommands and/or parameters and/or parameter values. The templates are used to generate examples that respond to a user query for assistance in using a particular command. A weighted elastic search is used to search for templates having a close similarity to fields in the template with the target command at issue. The templates are then used to format examples of the usage of a command which is sent back to the user.

These and other features and advantages will be apparent from a reading of the following detailed description and a review of the associated drawings. It is to be understood that both the foregoing general description and the following detailed description are explanatory only and are not restrictive of aspects as claimed.

DETAILED DESCRIPTION Overview

The subject matter disclosed herein pertains to a command assistance tool for a browser-enabled command line interface of a cloud service. The command assistance tool provides examples illustrating the correct syntax for a command used to manage resources of a cloud service. A command may include subcommands and/or parameters which may not be known by a user. The command assistance tool provides a fast and convenient means to obtain examples illustrating the correct usage especially when there is limited documentation. A cloud service may have a vast amount of commands with numerous subcommands and/or parameters making it difficult for a user to remember the correct syntax needed to perform a function.

The command assistance tool learns from usage patterns of a command in combination with different subcommands, parameters and parameter values. These usage patterns may come from script programs that use the commands, telemetric data, and user documentation. The usage patterns are used to form templates for the more frequently used commands. There may be multiple templates for a command where each template has a different combination of subcommands and/or parameters and/or parameter values. Default parameter values are learned from the documentation and are included in the templates. Personalized values for the parameters may be learned from telemetric data and included in the templates.

The templates are stored in a repository and utilized to create examples. In one aspect, the templates are formed as JSON objects that are retrieved using a weighted elastic search. A weighted elastic search is used to select those templates that are closely relevant to different fields in the JSON object that are more likely to relate to the intended command usage. The templates are then used to generate examples illustrating the correct syntax needed to invoke the command.

Attention now turns to a further discussion of the system, devices, components, and methods utilized in the machine learning comparison tool.

System

FIG. 1 illustrates a block diagram of an exemplary system 100 in which various aspects of the invention may be practiced. As shown in FIG. 1 , system 100 includes a client device 102 communicatively coupled to a cloud service 104 through a network 106. The cloud service 104 includes a number of resources (e.g., applications, virtual machines, libraries, services, databases, storage, etc.) that are made available to one or more client devices 102 through the Internet. The cloud service 104 is composed of one or more third-party servers. Examples of a cloud service include Microsoft Azure, Google Cloud, and the like.

A client device 102 includes a browser or rich client application 108 that is configured to execute a command line interface 110. The command line interface (CLI) enables a user on a client device 102 to access resources on the cloud service through text-based commands. Commands are entered into a command prompt or input field of the CLI and transformed into Representational State Transfer (REST) Application Programming Interfaces (API)s. The REST APIs are service endpoints that support a set of HTTP operations or methods to create, retrieve, update, delete or access resources on the cloud service.

In order to facilitate usage of the command line interface 110, the cloud service 104 has a command assistance tool that provides examples of the correct syntax of a command to perform a particular function from a set of templates. The command assistance tool 118 generates the templates from different sources and uses the templates to respond to queries for assistance on the usage of a command.

A template is an example of the correct syntax of a command for an intended purpose. A command includes a command name and may include one or more sub-commands and/or parameters or arguments. There may be multiple templates for a command with each template having a different sequence of sub-commands and parameters. A parameter includes a parameter value. The template generation engine 128 generates the templates from various sources which include telemetric data, script repositories, and/or documentation. Telemetric data 138 is obtained from monitoring the usage of the commands at the cloud service 104 through a telemetry engine 132. The telemetry engine 132 monitors the commands that are executed in the cloud service 104 and generates usage patterns of its syntax.

The template generation engine 128 also obtains usage patterns from scripts stored in one or more script repositories 136 and from documentation 134. A script is a list of commands presented in a file written in a script programming language (e.g., JSON, JAVASCRIPT, HTML, XML, etc.) that are performed sequentially by an interpreter. A script repository 136 is a file archive and web hosting facility that makes available scripts or programs written in a scripting language. A script repository 136 includes external repositories, such as GitHub, BitBucket, CloudForge, and internal repositories, that are not publicly accessible, such as a script repository associated with the cloud service.

The template generation engine 128 also obtains command usage examples from various forms of documentation 134, such as online documentation. It should be noted that the disclosure is not limited to the sources described herein and that other sources may be used to obtain usage patterns of a command syntax.

The template generation engine 128 uses the usage patterns from the various sources to generate templates which are stored in a template repository 130. In one aspect, the template repository 130 may be implemented as a database of JSON objects accessible using an elastic search.

The command assistance tool 118 receives requests for command syntax examples from users of the cloud service. One or more examples are selected from the templates that are stored in the template repository 130. The requests are input through the command prompt in the client device 102 and transmitted to the cloud service 104. The example generation engine 120 extracts keywords from the request, obtains one or more templates matching the extracted keywords, updates the parameter values for the parameters in the template, if any and returns to the client device examples, based on the found templates.

Attention now turns to FIGS. 2A-2C which illustrate the command line interface for the Microsoft Azure cloud service. It should be noted that the disclosure is not limited to the commands and examples shown in FIGS. 2A-2C and that these examples are used to illustrate the teachings set forth herein.

Turning to FIG. 2A, there is shown an exemplary instruction requesting assistance with the syntax of the command az vm create 204. The command az vm create pertains to the creation of a virtual machine on the cloud service. In the example shown in FIG. 2A, the command prompt is the string $ az find which instructs the command assistance tool to find examples of the correct syntax associated with the command vm create. The command assistance tool responds with the response I'm an AI robot; Here are the most common ways to use [az vm create] 206.

Three examples are provided that reflect the most frequently used ways that the az vm create command is used. The first example 208 shows the correct syntax of the az vm create command:

az vm create -resource-group MyResourceGroup -name MyVirtualMachine.

In this example, the az vm create command specifies the creation of a virtual machine with the parameters --resource-group and --name. The character ‘--’ denotes a parameter. Not all command may have a parameter. In this particular cloud service, resources are allocated within a resource management group that has its own name identified by the resource-group parameter having a default value, MyResourceGroup. The virtual machine is also identified by the name parameter whose default value is MyVirtualMachine.

The second example 210 shows another correct syntax of the az vm create command:

az vm create --n MyVM --g MyResourceGroup --image UbuntulTS.

In this example, a default Ubuntu virtual machine is created with automatic Secure Shell (SSH) authentication. An Ubuntu virtual machine is a virtual machine that runs the Ubuntu operating system. SSH is a cryptographic network protocol that is used to establish communications between the client and the cloud service. In this example, the --n parameter identifies the name of the virtual machine, MyVM, the --g parameter identifies the resource group, MyResourceGroup, and the --image parameter identifies the operating system, UbuntulTS.

The third example 212 describes the creation of a default Windows Server virtual machine with a private IP address:

az vm create --n MyVM --g MyResourceGroup --public-ip-address “ ”--image Win2012R2DataCenter.

In this example 212, the command uses the name parameter, --n, to identify the name of the virtual machine, MyVM, the group parameter, --g, to identify the resource group, MyResourceGroup, the public IP address parameter, --public-ip-address, to identify a private IP address, “ ”, which is blank, and the image parameter, --image, to identify the operating system, Win2012R2DataCenter.

FIG. 2B illustrates a request for examples on how to use the az vm command. The request 222 takes the form $ az find vm. The az vm command has a large number of subcommands that are associated with it, such as az vm create, az vm show, az vm list, az vm encryption status, etc. In this instance, the command assistance tool provides the most frequently used subcommands that are associated with the az vm command. As shown in FIG. 2B, the automatic response: I'm an AI robot; Here are the most common ways to use [az vm] 224 is provided along with three examples.

The first example 226 indicates the syntax of the command to show the details of a virtual machine:

az vm show --name MyVirtualMachine --resource-group MyResourceGroup

where the parameter, -name, identifies the name of the virtual machine, MyVirtualMachine, and the parameter, --resource-group, identifies the name of the resource group, MyResourceGroup.

The second example 228 indicates the syntax of the command for listing the details of a virtual machine:

az vm list -output table, where the parameter, --output, indicates that the details are to be formatted in a table.

The third example 230 indicates the syntax of the command to show the encryption status of a virtual machine:

az vm encryption show --name MyVirtualMachine -resource-group MyResourceGroup, where the parameter, --name, identifies the name of the virtual machine, MyVirtualMachine, and the parameter, --resource-group, identifies the name of the corresponding resource group, MyResourceGroup.

It should be noted that in the examples shown in FIGS. 2A-2B, the values for the parameters contain default values. For example, the name, MyResourceGroup, is the default value for the --resource-group parameter and the name MyVirtualMachine, is the default value for the -name parameter. The command assistance tool has the capability to include in the examples, personalized values for the parameters instead of the default values. The personalized values are those parameter values associated with known resources on a user on the cloud service. The personalize value can be ascertain by the command assistance tool issuing commands to obtain them or from tracking a user's telemetric data.

FIG. 2C illustrates examples where personalized parameter values are used instead of the default values. In FIG. 2C, a request is received for the az vm create command. In order to personalize the parameter values, the command assistance tool discovers the current values for the name and resource group parameters. This can be accomplished by the issuance of the az group list| head which returns the names of the resource groups the user has allocated 234. As shown in FIG. 2C, the user has two affiliated resource groups 236: clirg and clirg1, which are located in westus and have a status of succeeded. Once these parameter values are obtained, the command assistance tool uses the personalized parameter values in the examples.

The introductory message 240 is returned in response to the request 238. The first example 242 shows how to create an Azure virtual machine using the command syntax including the personalized parameter values: az vm create -g clirg -n webVM1, where the resource-group name parameter, -g, includes the personalized value, clirg, and the virtual machine name parameter, -n, includes the personalized value, webVM1.

The second example 244 shows how to create a default Ubuntu virtual machine with automatic SSH authentication with personalized parameter values:

az vm create -n webVM1 -g clirg -image UbuntuLTS, where the name parameter, --n, includes the personalized value, webVM1, and the resource-group parameter, --g, includes the personalized value, clirg.

The third example 246 shows how to create a default Windows Server virtual machine with a private IP address with personalized parameter values:

az vm create -n webVM1 -g clirg -public-ip-address “ ”--image Win2012R2DataCenter, where the name parameter, --n, includes the personalized value, webVM1, and the resource-group parameter, --g, includes the personalized value, clirg.

Attention now turns to a description of the template repository. In one aspect, the template repository is structured as a JSON array so that the array can be indexed. The JSON array can be searched using an elastic search that adds an inverted index to improve the speed of the template retrieval. Every field in the JSON array is associated with an inverted index. An inverted index contains a list of all the unique words that appear in the document and for each unique word a list of the documents in which it appears.

FIGS. 3A-3B illustrate an exemplary JSON array 300 that the command assistance tool generates to store the templates. As shown in FIG. 3A, this JSON array is a collection of name/value pairs for the group command, az vm. A group command is a command that has multiple sub-commands. The field 302, tag, identifies the array as pertaining to the values cli and azure. The answer field 304 is a description of the associated command. The children field 306 identifies the indices of the sub-commands associated with the group command, az vm. In this example, there are nineteen subcommands represented with indices 1290 through 1307.

The question_keywords field 310 identifies keywords associated with this command, such as az vm. The id field 314 is an identifier and represents a value, 1308, used to search for this object. The question field 316 is the command for this object. The link field 320 contains the URL having additional information about the command.

FIG. 3B illustrates an exemplary JSON object for the az vm show subcommand associated with the az vm group command. The tag field 332 identifies that the classification that the object pertains to, such as cli. The answer field 334 identifies the description of the command. The question_keywords field 338 identifies keywords associated with the command, such as, az vm show, show, details, resource, and query. The link field 340 is empty but would contain the URL having additional information about the subcommand. The id field 342 represents a value, 1290, used to search for this object. The question field 344 contains a text string representing the correct syntax for the command. In this instance, the response in the question field contains frequently-used parameters for this subcommand, such as, --show-details, --name, --query, and -resource-group and corresponding default values, such as MyVM, and MyResourceGroup.

Methods

Attention now turns to a description of the various exemplary methods that utilize the system and devices disclosed herein. Operations for the aspects may be further described with reference to various exemplary methods. It may be appreciated that the representative methods do not necessarily have to be executed in the order presented, or in any particular order, unless otherwise indicated. Moreover, various activities described with respect to the methods can be executed in serial or parallel fashion, or any combination of serial and parallel operations. In one or more aspects, the method illustrates operations for the systems and devices disclosed herein.

FIG. 4 represents an exemplary method 400 for generating the templates. Referring to FIGS. 1 and 4 , a template is generated for the most frequently-used commands (block 402). A template contains the data needed to respond to a request for the syntax of a command. A template is derived from usage patterns of the command. The sources for a template include user documentation, telemetric data, and/or script repositories. A telemetry engine 132 monitors the execution of the commands at the cloud service 104 and generates the telemetric data 138 from these commands. The template generation engine 128 scans the telemetric data 138 to determine the most frequently-used commands. There may be a frequency threshold used to limit the number of commands for which a template is generated.

For each command in the command set (block 404), the template generation engine 128 generates one or more templates for the command (block 406). The template may be constructed as a JSON object or array similar to what is described in FIGS. 3A-3B. The template generation engine 128 extracts data from various sources to construct the template with the data described above.

For example, a description of the command may be obtained from documentation. Relationships between commands, such as which is a group command and which are the sub-commands of a group command may be obtained from the documentation and input into the template. The parameters required for a command may be obtained from the documentation and from the telemetric data.

In some instances, a parameter may be optional and in other instances, a parameter may be required. The documentation may not describe the parameters needed for a command. In this instance, the template generation engine parses the programs or scripts in the script repository to obtain usage patterns of a command. It can be determined from these usage patterns whether or not a command requires a parameter or not and the number and types of parameters that are needed.

In some cases, a default value is used in the template as the value of a parameter. In other cases, the template generation engine 128 can determine a real value or personalized value for the parameter (block 408). The personalized value may be obtained from analyzing the documentation and from the scripts in the script repository (block 408).

The template generation engine 128 obtains the data for a command from the various sources and then inputs this data into a respective template (block 410). The template is then used to formulate a response to a query for the syntax of a command in the form of examples along with informative details. Attention now turns to FIG. 5 which shows an exemplary method 500 for generating the examples for a request.

Turning to FIGS. 1 and 5 , a request comes from a user's client device 102 through a command line interface 110 that is displayed via the user's browser 108 (block 502). In the command line interface 110, there is a command prompt 112 through which the user requests assistance with the syntax of a command. The command prompt for the assistance may be in the form of the character “?” which is combined with the command az find and the name of the command. The command may be a group command that is associated with a number of subcommands. For instance, a group command may be az vm which has a number of subcommands, such as create, show, list, etc. The name of the command may be the group command (e.g., ? az find vm) or the group command combined with subcommands and/or parameters (e.g., ? az find vm create). In either case, the example generation engine 120 parses the request to extract out the command, which in this case is the text after az find.

The example generation engine 120 then searches for one or more templates matching the command (block 504). In one aspect, the example generation engine 120 uses an elastic search engine to perform a weighted elastic search on the JSON objects or templates to find one or more templates that have a close relevance to the target command.

An elastic search is a full text search that uses a Boolean model to find matching templates and a practical scoring function that generates a score for a template in order to rank the templates by relevance to the command at issue. The elastic search consists of an analysis phase and a relevance phase. In the analysis phase, each block of text is converted into an inverted index. In the relevance phase, a score is generated for each document which identifies how similar a full-text field is to the full-text query string.

A weighted elastic search gives more weight or relevance to documents based on certain fields of the JSON document. In one aspect, a weight is used to denote the importance of certain fields of the template than others. For example, referring to FIG. 2A, the index for the elastic search is based on the question_keywords field (i.e., az vm create) and the question field (i.e., az vm create-resource group MyResourceGroup-name MyVirtualMachine). The index will give more weight to question_keywords than questions. This can be done through a configuration file that specifies the weights as follows:

  “weights”: {   “question_keywords”: 6,   “question”: 3  }

When the cloud assistance tool uses the elastic search engine to search for az vm create, the elastic search engine will assign a high score to the template where az vm create occurs in the question_keyword field. The templates are returned in ranked order and the cloud assistance tool takes a predetermined number of templates to use as the examples.

The retrieved templates are then used to format the response with examples derived from the templates (block 506). For example, the response may include the formatted message, I'm an AI robot; Here are the most common ways to use [extracted command], where extracted command includes the command extracted from the request. In addition, for each template that is retrieved, the example generation engine 120 formats an example including a description which is taken from the answer field of the corresponding JSON object. The syntax of the command is taken from the question field of the corresponding JSON object.

Next, the example generation engine 120 replaces the default parameter values with personalized parameter values when the command has parameters (block 508). The question field may include default values for the parameters used in the command. The example generation engine 120 may obtain personalized values in place of the default values for a parameter. For instance, for the az vm create command, the example generation engine 120 issues an az find vm list command to obtain the name of a virtual machine that is allocated for the user and a resource-group name that is associated with the user. If these names exist, the example generation engine 120 substitutes these values in place of the default values of a parameter.

Upon completion of the formation of the examples, the example generation engine 120 returns the examples to the client device which are displayed in the command line interface (block 510).
